Different Types of Expanded Metal expanded metal

As expanded metal has a high strength to weight ratio and is easy to use, it makes it ideal for many uses. Expanded metal can be used for security fencing, fence grating, walkways, ventilation systems as well as architectural or decorative purposes.
 

A wide variety of expanded metal is available, including flattened, standard (raised), grating, catwalk grating, and designer. Expanded metals have their own unique characteristics and advantages, which are why choosing the right expanded metal for a given application depends on such factors as strength, durability, and appearance. We will discuss all of these types in more detail, as well as their advantages and applications.
 

What Is Expanded Metal?

 
The origin of the expanded metal creation process dates back to the 1880s in Hartlepool, UK, where it was initially developed and copyrighted. Despite technological advancements, the contemporary method of expanding metal closely resembles the original technique.

Expanded metal is crafted from a solid metal sheet, with materials like stainless steel, aluminum, steel, titanium, and copper commonly used. The sheet undergoes cutting and stretching through industrial machinery, resulting in a mesh with diamond-shaped openings. Various other patterns can be achieved through this process.

The open-to-closed mesh area ratio determines the space available for light, air, and water passage, and this ratio can be tailored to suit specific mesh applications. Starting from a small steel sheet and culminating in the production of a large mesh, the process renders the material lightweight and cost-effective, making it an economical choice.

The versatility of expanded metal broadens its applications, finding use across various industries. While permitting the passage of air and light, expanded metal boasts robust strength and durability.

The diamond shape excels in energy absorption and exhibits minimal deformation after installation. Other design variations take into account the size and angles of the shapes, evaluating their capacity to absorb energy effectively.
 

How Is Expanded Metal Made?

 
The production of expanded metal commences with a metal sheet, undergoing cutting and stretching processes. These actions uniformly expand the cuts, forming diamond-shaped apertures. Notably, the expanding process generates no metal waste, rendering expanded metal an eco-friendly product. As previously mentioned, expanded metal originates from a single sheet of any metal. An industrial cutting machine traverses back and forth, making alternating cuts to achieve a specific shape. Various knife patterns can be employed to cut the sheet into diverse shapes and sizes. The primary objective of creating expanded metal is to stretch it, requiring only a small metal piece for the process.

Expanded metal machines serve multiple functions, with certain processes necessitating the use of multiple machines. The conventional approach involves expanding the metal sheet in a press to create diamond-shaped voids. Subsequently, a flattening machine is utilized to level the metal, followed by a shearing and slitting machine that cuts and forms the holes. The specific process may vary based on available resources and requirements.
 

Different Types of Expanded Metal

 
There are 5 main types of expanded metals: standard expanded metal, flattened expanded metal,designer expanded metal,expanded metal catwalk grating and expanded metal grating. They all start as a metal sheet, but evolve into their respective types.
 

What Is Standard (Raised) Expanded Metal?

 
Standard expanded metal, also known as raised expanded metal, proves to be a versatile material suitable for various applications. The distinctive raised pattern of diamond-shaped openings is achieved through the process of slitting and stretching the sheet metal. Standard expanded metal is ready for use after cutting, whereas additional manufacturing steps are required for flattened expanded metal.

This type of expanded metal is offered in diverse materials, including aluminum, carbon steel, galvanized steel, and stainless steel. It finds common usage in decorative and architectural features, filtration systems, and protective barriers.

A notable advantage of standard expanded metal lies in its generous open area percentage, facilitating improved airflow and visibility. The increased open area makes it an excellent choice for applications such as ventilation systems or security screenings. The raised diamond-shaped openings provide a non-slip surface, ensuring good traction and making it suitable for flooring in industrial and commercial areas.

The strength and durability of standard expanded metal further make it suitable for heavy-duty applications where safety and stability are paramount. In essence, standard expanded metal emerges as a versatile and enduring material, easily customizable to meet diverse application requirements.
 

What Is Flattened Expanded Metal?

 
Flattened expanded metal refers to a specific type of expanded metal that undergoes additional processing to achieve a flattened or smooth surface. The standard expanded metal, characterized by its raised pattern of diamond-shaped openings, is subjected to a flattening process to produce this variant.

The manufacturing process involves slitting and stretching a metal sheet, creating the raised pattern in standard expanded metal. To produce flattened expanded metal, the standard version undergoes a secondary process. This process typically involves passing the raised expanded metal through heavy rollers that flatten the surface, resulting in a smoother and level finish.

Flattened expanded metal shares similarities with its standard counterpart in terms of material options, including aluminum, carbon steel, galvanized steel, and stainless steel. However, the additional flattening step imparts unique characteristics to the flattened variant, making it suitable for specific applications.

The flattened surface offers benefits such as improved aesthetics, increased surface area for certain applications, and enhanced versatility in decorative and architectural uses. It retains the strength and durability associated with expanded metal while providing a different visual and functional profile compared to the standard raised pattern.
 

What Is Designer Expanded Metal?

 
Designer expanded metal stands out with its distinctive patterns and designs, making it a perfect choice for architectural and decorative applications. Specifically crafted to produce unique and decorative patterns, this type of expanded metal can be customized to fulfill specific aesthetic or functional requirements. Unlike standard expanded metal with its typical diamond-shaped openings, decorative expanded metal features various shapes, textures, and designs.

Architects frequently incorporate designer expanded metal into building facades, decorative screens, and interior designs. Its versatility extends to applications like shading, security, and privacy. Available in materials such as stainless steel, aluminum, brass, and copper, designer expanded metal offers a range of options.

The manufacturing process for designer expanded metal involves cutting and stretching metal sheets to form a mesh-like structure, akin to the production of standard expanded metal. However, the process for designer expanded metal is more precise and controlled to achieve the desired intricate patterns. Additionally, the metal sheets used in designer expanded metal are typically thinner, providing greater flexibility and ease of manipulation.

The thinness of the metal enables the creation of more intricate designs, empowering architects and designers to fashion unique and detailed patterns. With its distinctive design, durability, and versatility, designer expanded metal proves to be an excellent choice for various architectural and decorative applications.
